Irving Penn is widely recognized as one of the 20th century’s greatest photographers. Vogue’s longest-standing contributor, Penn revolutionized fashion photography in the postwar era. Using neutral backgrounds, he emphasized models’ personalities through their gestures and expressions. The exhibition includes 196 photographs, spanning every period of Penn’s nearly 70-year career. The works range from early documentary scenes, celebrity portraits, and workers with the tools of their trades to abstract nudes and fashion studies. A special section of images from San Francisco’s Summer of Love features hippies, members of the Hells Angels Motorcycle Club, and local rock bands the Grateful Dead and Big Brother and the Holding Company.
